Create Smooth Dropdown on iOS swift 5


Welcome back to my blog guys, today I want to share something about dropdown thing. Dropdown is not something that is exist on iOS UIKit. On iOS we have something similiar to dropdown menu Android that is Picker View. But sometimes we need to create UI same as Android. It will have better User Expierence.

Fortunetely some people have dealt with our problems. So they created the dropdown menu in their own. What I have used is what I'm gonna share today. It's DropDown created by jriosdev, I will share github link on below, don't worry about it.

You install dropdown in your project using CocoaPods, or You just simply add Dropdown library by creating class named DropDown and add Textfield in your Storyboard then change class Textfield to Dropdown. For more details how to install this library you can check their github. I will give the link github below OK.

But we have some problem about the animation when dropdown menu clicked. It makes the dropdown slow, but fortunely you can remove the bounce animation actually, In DropDown.swift change all the UIView.animate to withDuration: 0.0 and delay: 0.0 would fix it. Or you just copy paste code below in DropDown.swift. After that try to run your app and see If there's no animation again and slow issue is solved :D.

This is the full code I have edited :


Thanks for visiting my simple blog. I hope It will help you have a nice dropdown in your app. If you have any question, please feel free to ask. I'm glad I can help you all guys. Thanks.

How to restart the app with flutter Android and iOS

Hi all, welcome back to my blog. And today lesson is about flutter again. I have a little problem when trying to resart the app directly from the app. So what I mean is I want to restart the app after users do something. Because if I don't do it, the app flow will be bad and the data that I want to refresh will be failed. So in my use case in my app is I want to restart the app after user sign in or sign out in my app. The reason is I need to restart all of the previous state. That's the easy way I can do, and I have some problems with camera plugin. The problem is happened only on android, so when you click sign in google/facebook, there'll be new page native from their sdk and making the app in inactive status. That'll will make camera bug, and it will make the app crash.

How to have ConstraintLayout inside ScrollView and ScrollView inside ConstraintLayout Android

Hai guys, last week I found a unique way to create layout Android look. You can see the title, that's actually what I want. I know it sounds weird but sometimes we need to create something that we might curious if it's in o n the internet or not. Why I'm using ConstraintLayout because it's almost same with iOS xcode. There is constraint where you can set top constraint, bottom constraint, left constraint and right constraint. So it's easy for me to design like what I want. But it's personal, it depends on you too. And fortunely you can combine ScrollView and ConstraintLayout. Because you need to worry when the height of your layout is high than real device height. And if you don't use UIScrollview your component will be unseen when the height of device is more small than layout that we design. Like my app, I want to use ConstraintLayout and ScrollView together. Maybe it can do with RelativeLayout or others layout. But something special that I want i
